Governance 

We are committed to climate action and believe that transparency, governance and oversight from the top are foundational to our success. Crestwood’s carbon management and climate strategies are driven primarily by the Board of Directors' Sustainability Committee. We report our emissions quarterly to the Board of Directors through an internal multi-discipline Carbon Management Working Group established in 2020. The Board’s Sustainability Committee is also responsible for approving the enterprise-wide compensation goal that is tied to a reduction in methane emissions intensity. 

To build responsibility across the organization, we tie sustainability key performance indicators (KPIs) to employee compensation. 

Climate Change Strategy

We believe our climate change strategy encompasses a practical, continuous improvement approach to reduce industry emissions while simultaneously meeting the world’s growing energy demand. Crestwood’s strategy is to efficiently manage the operations of its vital infrastructure to reduce unnecessary GHG emissions and mitigate the potential for fugitive and process emissions.

Managing GHG emissions, including methane, is an integral part of our overall environmental management program. We work collectively to meet or exceed all regulatory requirements, reduce the emissions intensity of our operations and use cleaner sources of energy where possible. 

Carbon Management Plan

In January 2022, we published our first Carbon Management Plan. This plan outlines Crestwood’s near-term emissions reduction goals, activities and strategies that we intend to implement as we expand our midstream gathering and processing asset portfolio. Our Carbon Management Plan is an authentic approach to managing our critical midstream infrastructure, and it is centered on our public commitment to reduce greenhouse gas (GHG) emissions intensity annually.

Evaluating our Greenhouse Gas Emissions Performance:
Metrics and Targets

Close

In 2021, our absolute Scope 1 emissions decreased 9 percent due to operational changes relating to process optimization of our glycol dehydrators, higher bleed pneumatic device replacement with low-bleed units and reduced emission blowdowns across our assets companywide.

Close

Our Scope 2 emissions decreased 34 percent due to optimizing our power usage across our assets as well as updated EPA eGRID emissions factors that were published in April 2022.

Close

Since 2018, we have calculated our GHG emissions intensity by metric tons of carbon dioxide equivalents (CO2e) per $MM Adjusted EBITDA. Using this method for a GHG intensity rate, we measured a 19 percent reduction from 2020 levels. In 2021, we began using a volumetric intensity calculation method as outlined in our Carbon Management Plan and measured by metric tons of carbon dioxide equivalents (CO2e) per thousand barrel of equivalent (BOE) which resulted in a 6 percent reduction from 2020 levels. These GHG intensity reductions were due to increased operational efficiencies and our continued improvements surrounding our GHG data aggregation.

Close

We have tied our methane emissions intensity rate to all executive and employee compensation in 2021 and in 2022. Our methane emissions intensity rate measured by metric tons per million standard cubic feet per day (Mscf) throughput decreased 30 percent in 2021 from 2020 levels and 52 percent from 2019 due to our increased focus on methane management including an enhanced approach to leak, detection and repair (LDAR) and incorporating actual operational data instead of using emissions factors on the glycol dehydrators at our Jarvisville compressor station in the Marcellus. With further efficiency improvements planned for the coming years, we anticipate further methane intensity reductions.

(All emission reductions are from 2020 levels)

Operational emissions from midstream companies account for a small portion of total GHG emissions across the value chain. While our current focus is to reduce Scope 1 and Scope 2 emissions, Crestwood plans to begin Scope 3 emissions analysis in early 2023.

Main Sources of GHG Emissions

In 2021, we undertook a data visualization process to help us identify our sources of emissions by asset and equipment type. We found that approximately 70 percent of our Scope 1 emission comes from engines or the combustion of fuel to drive our compressors. Therefore, we are focusing our efforts on analyzing multiple options, including equipment replacement, operational changes and technological innovations, to decrease our emissions.

Assessing and Managing Climate Risk

Understanding, managing and reporting on climate-related financial risks and opportunities is critical for our business. We integrate climate-related considerations into key business planning and our annual Enterprise Risk Management (ERM) process. It is the responsibility of our executives and management team to implement this risk assessment and management process. 

We have identified several potential climate-related risks. This includes physical and transition risks, e.g., effects of climate change on our assets and reduced demand for fossil fuels due to the implementation of policies designed to reduce GHG emissions. We have outlined our potential physical and transition risks and opportunities below, along with brief descriptions of the potential financial impacts. 

In late 2022, we plan to conduct a full Task Force for Climate-related Financial Disclosures (TCFD)-aligned scenario analysis and physical risk assessment of Crestwood operations. We will publish the results of this analysis in our 2022 sustainability report.

Continuous Methane Monitoring Pilot

In late 2021, we initiated our continuous methane emissions monitoring pilot program to better enhance our approach to methane detection. Our first pilot is being conducted at the Appaloosa Compressor Station on our Jackalope System, located in Wyoming. We installed ChampionX SOOFIE monitors, a metal oxide sensor that continuously records several methane measurements a second. We are currently utilizing the devices to better understand our methane emissions. 

We are also beginning to pilot two to three additional next-generation applications in multiple basins as part of our ongoing initiatives to find more robust and faster ways to detect and mitigate emissions. Based on results from the pilot program, Crestwood aims to deploy continuous methane emissions monitoring devices at key operations while improving its emissions performance by the first quarter 2023.

Upstream Producer Partnerships

Reducing emissions across the natural gas value chain is an industry-leading responsible action and aligns with key business strategies in the industry. In 2021, we partnered with an upstream producer to install vapor recovery units (VRUs) on the tanks of their production facilities. This is our first step in partnering with our upstream suppliers and we are pleased that the installation of VRUs at this facility resulted in a seven percent reduction in low pressure emissions. We look forward to finding new opportunities to work with our suppliers to optimize production and minimize emissions.

As we continue to evaluate opportunities across our assets, we are excited to contribute to reducing emissions through unique partnerships, such as this. In 2020, Crestwood published a Flaring Minimization Policy and rolled out associated training to employees to provide education on the benefits of reducing flaring and ensure emission reductions and sustainability goals are met.

Looking Ahead

Our focus in 2022 is to set a strong foundation, with an emphasis on data management. In early 2022, we incorporated GHG emissions performance into our due diligence process. We are committed to going beyond U.S. EPA emission factors and are prepared to invest in the necessary technology for quantitative emissions calculations and data. Therefore, we expect to:
